Che-Liang Chiou	9522b84029	Add EntryWiped to pack_firmware_image ... EntryWiped takes a byte value wipe_value of range [00:ff] as one of its arguments that pack_firmware_image uses the value to "wipe" the entry.

Che-Liang Chiou	b6a29ad339	Allow overlap between "pure" fmap areas ... Firmware specification has several sections that are overlapped. This CL allows limited overlapping that only "pure" fmap areas can be overlapped. See also CL=6694022,6696016 for its application.
